I wonder if the marketing trick is they leave out something popular, and then add it in an update at the end, so that users can't complain.

For example, can't complain about iPhone not having copy/paste because they eventually added it. A couple years from now we won't be able to complain about iPad not having multi-task, because the fans shall defend the iPad by referring to the feature update that was called multi-tasking.

Leave something out that you know you can easily fix later, and you shall instantly be able to turn your negative publicity into a positive whenever you want.
